Patent number: 11948951Abstract: The invention relates to a wide spectrum multi-band detection structure with selective absorption enhancement and its preparation method. The structure comprises a plurality of sub-pixel units capable of detecting incident light in different bands. Each sub-pixel unit is composed of a square well-shaped microstructure array and a metal lower electrode (2), a photosensitive layer (3) and an upper electrode (4) on the surface thereof. The size and array spacing of square well-shaped microstructures in different sub-pixel units are determined according to the detection bands of the sub-pixel units where they are located. The upper openings of the square well-shaped microstructures are hollow to form a resonant cavity, and the adjacent square well-shaped microstructures in the same sub-pixel unit form a resonant cavity, thus solving the problem that the detector structure in the prior art cannot simultaneously realize visible light-near infrared multi-band absorption enhancement detection.Type: GrantFiled: November 23, 2019Date of Patent: April 2, 2024Assignee: Xi An Technological UniversityInventors: Huan Liu, Weiguo Liu, Yan An, Minyu Bai, Jun Han, Zhuoman Wang, Jiaxing Hu, Changlong Cai

Publication number: 20220008425Abstract: The present invention discloses a pharmaceutical composition for treating B-cell lymphoma, including a PI3K/AKT signaling pathway inhibitor and a chemotherapeutic drug, and further including a monoclonal antibody targeting CD20, such as rituximab. The pharmaceutical composition provided by the present invention is particularly suitable for the treatment of relapsed/refractory B-cell lymphoma. Given the critical role of cancer stem cells (CSCs) in the process of metastasis and drug resistance, the present invention proposes a new pro-differentiation therapy (PDT) strategy to cope with CSCs, i.e., to determine the decisive signaling pathway that maintains stem cell sternness and then promotes CSC differentiation by interfering with the pathway. Differentiated cells are eventually sensitive to conventional therapies, such as chemotherapy.Type: ApplicationFiled: April 10, 2019Publication date: January 13, 2022Inventors: Weiguo HU, Jianfeng CHEN

Publication number: 20160082104Abstract: The invention features peptide fragments containing domain 4 of the Streptococcus intermedius intermedilysin (ILY) protein and the use of these fragments to sensitize cancer cells to antibody-based anticancer treatments. The invention also features use of these fragments to treat patients infected with microbial pathogens expressing CD59 or CD59-like molecules. CD59 receptor activity has been associated with decreased sensitivity to therapeutic and endogenously produced antibodies. Administration of ILY domain 4 polypeptides is sufficient to inhibit CD59 receptor activity while avoiding the general toxicity associated with full length ILY.Type: ApplicationFiled: September 28, 2015Publication date: March 24, 2016Applicant: PRESIDENT AND FELLOWS OF HARVARD COLLEGEInventors: Xuebin QIN, Weiguo HU
